About Us

Simperium, Inc. is a startup based in San Francisco. We help developers build apps that synchronize content across devices and the web.

We built Simplenote, an app for keeping notes. An early version of our Simperium platform is used by dozens of 3rd-party apps and services to synchronize text with the Simplenote ecosystem. We’re now building the next major version of the Simperium platform.
